Meet the Team

For Quinnten Alston, the Quantico program is the realization of a lifelong fascination with horse breeding and pedigrees. He began riding at the age of 5 and formed a childhood passion that would endure through his adult years. Professionally, Quinnten began modestly by cleaning stalls for Mo Swanson's Rolling Stone Farm in Slatington, PA in 2009. Within a few months, he was handling as a professional at breed shows and inspections under the guidance of Bob Orton. Quinnten gained a following for his carefully curated and vibrant approach to handling along the East Coast at prestigious venues like Dressage at Devon, Dressage at Lexington, and Morven Park. Over the years, he has presented the Grand Champion at Dressage at Devon a total of 5 times.

After Rolling Stone, Quinnten spent three years honing his craft at the highly regarded training and breeding center Hilltop Farm in Colora, MD. Since 2017, he has served as an in-house rider and Sales Manager for the famous Iron Spring Farm in Coatesville, PA. Since 2012 he has made regular trips to Germany and Holland for networking and further education. Quinnten thoroughly enjoys talking horses with other breeders and riders and is the driving force behind the breeding direction of the program.

Jonathan Clark, the other half of Quantico Sporthorses, graduated from the University of Delaware in 1999 with a Bachelor of Science Degree in Animal Sciences.  While obtaining his degree, he started working for Select Breeders Services in 1994 by assisting with routine lab cleaning.  He eventually gained more responsibility in the company by becoming a freeze technician, helping to pioneer mobile lab use throughout the East Coast, and becoming the leader of the import/export department of SBS in Maryland.  Now, 25 years later, he dutifully holds the role of Director of Operations for the entirety of SBS.  Though he still enjoys occasionally spending time in the mobile lab, Jonathan oversees and assists the managers of SBS Veterinary Services, Select Breeders Services Headquarters in Maryland and Select Breeders Southwest in Texas with their daily operations. He plays a crucial role in the reproductive side of Quantico and also assists with final breeding season plans.

Married since July 2018, Quinnten and Jonathan do all of the work that goes along with managing and developing the Quantico program. Outside of their horses, they also enjoy traveling, the arts, good food, and spending time with family. They work closely with both Select Breeders Services in Chesapeake City, MD as well as Unionville Equine Associates in Oxford, PA for all of their reproductive needs from breeding to foaling.
